It is convenient to categorize grain boundaries according to the extent of misorientation between the two grains. Low-angle grain boundaries (LAGB) or subgrain boundaries are those with a misorientation less than about 15 degrees. Generally speaking they are composed of an array of dislocations and their properties and structure are a function of the misorientation. In contrast the properties of high-angle grain boundaries, whose misorientation is greater than about 15 degree… WebApr 6, 2024 · Oxide solid electrolytes (OSEs) have the potential to achieve improved safety and energy density for lithium-ion batteries, but their high grain-boundary (GB) resistance generally is a bottleneck. WebMay 22, 2016 · We investigate the mechanisms of incipient plasticity at low angle twist and asymmetric tilt boundaries in fcc metals.

WebThe uniaxial tensile test response of a H decorated Σ5 [1 0 0] twist grain boundary (GB) in face-centred-cubic Al has been examined with first principles. The impurity shows a strong tendency to relocate during loading. To capture these H movements, the standard model framework was extended to probe loading-unloading hysteresis. WebIn this case mixed dislocations must be used with a component of the Burgers vector in the grain boundary plane. The symmetries of the two crystal planes in contact at the grain boundary - even low-angle twist boundaries with a twist around the &lt;100&gt; axis can be joined on planes other than {100}. The complications that may arise because the ...
